Description

Technical Field

[0001] This utility model relates to the field of blood collection technology, and in particular to a clinical blood collection device. Background Technology

[0002] Clinical blood collection, or simply blood collection, refers to the process of obtaining blood samples from the human body through specific techniques and methods in clinical medical practice. It is mainly used for disease diagnosis, treatment monitoring, blood transfusion therapy, and medical research. After collection, the blood is placed into a blood collection bottle, and then the blood collection bottle is placed in a collection box.

[0003] A search revealed Chinese Patent Publication No. CN220391913U, which discloses a blood collection device for clinical research, comprising a housing with a lid on top. This invention utilizes the combined use of the housing, lid, casing, motor, cam, rocking plate, vertical plate, positioning plate, placement rack, compression pad, fixing plate, first spring, damper, heating shell, heating plate, temperature sensor, control box, groove, damping rod, buffer rod, base plate, and second spring to enable the blood collection device for clinical research to simultaneously hold multiple blood collection tubes and possess temperature control functionality. This solves the problem that existing blood collection devices for clinical research can only accommodate one vacuum blood collection tube, which is insufficient for collecting large quantities of different blood samples during clinical research. Furthermore, existing devices cannot meet the temperature requirements for placing and transferring blood samples in an environment close to human body temperature.

[0004] While the aforementioned device has some improvements, when the box contains blood collection bottles from different patients, staff need to manually remove and identify each bottle when using a specific one. When there are too many bottles, the workload of manual identification increases because it requires constant manual removal and identification, which is time-consuming and labor-intensive. Therefore, a clinical blood collection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clinical blood collection device, which aims to improve the problem in the prior art where when there are too many blood collection bottles, it is necessary to remove specific blood collection bottles one by one, which is quite troublesome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clinical blood collection device, comprising a collection box, a cover plate rotatably connected to the top right side of the collection box, a bottom plate in contact with the inner side wall of the collection box, a partition plate in contact with the inner side wall of the collection box, and a display mechanism provided at the top of the bottom plate.

[0007] The display mechanism includes a guide column, and the inner walls of the base plate and the partition are slidably connected with moving blocks. Multiple sets of moving blocks are rotatably connected to each other through an X-shaped connecting frame. The inner wall of the partition is elastically connected with a rotating column through a spiral spring. The inner side wall of the rotating column is rotatably connected with a connecting plate. The end of the connecting plate away from the rotating column is rotatably connected with an insert block. The inner wall of the cover plate is provided with a contact mechanism.

[0008] As a further description of the above technical solution:

[0009] One end of the spiral spring is fixedly connected to the inner wall of the partition, and the other end of the spiral spring is fixedly connected to the outer arc surface of the rotating column. The outer wall of the rotating column is rotatably connected to the inner wall of the partition.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the guide post is fixed to the inner wall of the collection box, and the outer wall of the insert is slidably connected to the inner wall of the partition.

[0012] As a further description of the above technical solution:

[0013] The top end of the X-shaped connecting frame is rotatably connected to the outer wall of the upper movable block, and the bottom end of the X-shaped connecting frame is rotatably connected to the outer wall of the lower movable block.

[0014] As a further description of the above technical solution:

[0015] The inner side wall of the collection box is provided with a insertion groove, and the outer wall of the insertion block is inserted into the inner wall of the insertion groove.

[0016] As a further description of the above technical solution:

[0017] The inner walls of the partition and the bottom plate are slidably connected to the outer arc surface of the guide column.

[0018] As a further description of the above technical solution:

[0019] The contact mechanism includes a connecting spring, one end of which is fixedly connected to the inner wall of the cover plate, and the other end of which is fixedly connected to a reset plate. The outer wall of the reset plate is slidably connected to the inner wall of the cover plate.

[0020] As a further description of the above technical solution:

[0021] A rubber strip is fixedly connected to the left side of the reset plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation between the collection box, partition, display mechanism and base plate and other structures, when multiple blood collection bottles need to be identified, the rotating column is rotated to release the partition limit, and then the partition is moved downward. At this time, the height of the X-shaped connecting frame will be shortened, so that the blood collection bottle is exposed to the mark, which facilitates manual judgment and identification, avoids manual removal of blood collection bottles for identification, and achieves the purpose of saving time and effort.

[0024] 2. In this utility model, through the cooperation between the cover plate and the contact mechanism, when the collection box needs to be transported, the cover plate is closed. At this time, the rubber strip contacts the top of the blood collection bottle, and the elasticity of the connecting spring applies pressure to the top of the blood collection bottle, thereby preventing the blood collection bottle from shaking and tipping over during the transport of the collection box, and ensuring the safety of the blood sample.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-2 This utility model provides an embodiment of a clinical blood collection device, including a collection box 1. A cover plate 4 is rotatably connected to the top right side of the collection box 1. The collection box 1 can collect blood collection bottles. The cover plate 4 can be opened or closed to carry the collection box 1. The inner side wall of the collection box 1 contacts a bottom plate 6 and a partition plate 2. The bottom plate 6 has a circular groove, and the partition plate 2 has a circular hole. The circular groove and the circular hole correspond to each other to place blood collection bottles. A display mechanism 3 is provided at the top of the bottom plate 6. The display mechanism 3 allows multiple sets of blood collection bottles to be moved upward to expose labels, thereby facilitating relevant personnel to quickly read the information of the blood collection bottles.

[0035] Reference Figures 3-5 The display mechanism 3 includes guide columns 303, with multiple sets of guide columns 303 for guiding purposes. Movable blocks 305 are slidably connected to the inner walls of the base plate 6 and the partition 2. Each movable block 305 has two parts: the upper movable block 305 is slidably connected to the inner wall of the partition 2, and the lower movable block 305 is slidably connected to the inner wall of the base plate 6. Multiple sets of movable blocks 305 are rotatably connected by an X-shaped connecting frame 304. When the overall height of the X-shaped connecting frame 304 decreases, the multiple sets of movable blocks 305 move outwards, causing the partition 2 and the base plate 6 to move closer together. The inner wall of the partition 2 is connected by a volute. A spring 307 is elastically connected to a rotating column 301. The rotation of the rotating column 301 releases the limiting position of the partition 2. A connecting plate 306 is rotatably connected to the inner side wall of the rotating column 301. An insert block 302 is rotatably connected to the end of the connecting plate 306 away from the rotating column 301. The rotation of the rotating column 301 drives the connecting plate 306 to rotate, thereby causing the insert block 302 to move towards the center to release the limiting position. Multiple sets of insert blocks 302 move synchronously. A contact mechanism 5 is provided on the inner wall of the cover plate 4. The contact mechanism 5 supports the top of the blood collection bottle when the cover plate 4 is closed.

[0036] Reference Figures 3-5One end of the spiral spring 307 is fixedly connected to the inner wall of the partition 2, and the other end of the spiral spring 307 is fixedly connected to the outer arc surface of the rotating column 301. The outer wall of the rotating column 301 is rotatably connected to the inner wall of the partition 2. The elasticity of the spiral spring 307 enables the rotating column 301 to have the functions of resetting and limiting. The bottom end of the guide column 303 is fixed to the inner wall of the collection box 1. The bottom plate 6 can support the guide column 303. The outer wall of the insert block 302 is slidably connected to the inner wall of the partition 2. The sliding of the two can guide the insert block 302 so that it can only move horizontally.

[0037] Reference Figures 2-4 The top end of the X-shaped connecting frame 304 is rotatably connected to the outer wall of the upper moving block 305, and the bottom end of the X-shaped connecting frame 304 is rotatably connected to the outer wall of the lower moving block 305. The X-shaped connecting frame 304 enables the bottom plate 6 and the partition 2 to move synchronously closer or open. The inner side wall of the collection box 1 is provided with an insertion groove 308. The outer wall of the insertion block 302 is inserted into the inner wall of the insertion groove 308. The two are inserted to fix the partition 2. The inner wall of the partition 2 and the bottom plate 6 are slidably connected to the outer arc surface of the guide column 303, and the two can move synchronously.

[0038] Reference Figure 1 and Figure 6 The contact mechanism 5 includes a connecting spring 502. One end of the connecting spring 502 is fixedly connected to the inner wall of the cover plate 4, and the other end of the connecting spring 502 is fixedly connected to a reset plate 503. The outer wall of the reset plate 503 is slidably connected to the inner wall of the cover plate 4. The elasticity of the connecting spring 502 enables the reset plate 503 to have the functions of reset and contact, thereby supporting the top of blood collection bottles of different heights. A rubber strip 501 is fixedly connected to the left side of the reset plate 503. The rubber strip 501 corresponds to the round hole, thereby ensuring that the reset plate 503 and the top of the blood collection bottle achieve flexible contact through the rubber strip 501.

[0039] Working principle: When it is necessary to read the blood collection bottle information, the relevant personnel rotate the rotating column 301. The rotating column 301 is elastically connected to the partition 2 through the spiral spring 307. When the rotating column 301 rotates, it will drive the connecting plate 306 connected to it to move. The other end of the connecting plate 306 is rotatably connected to the insertion block 302. As the connecting plate 306 rotates, the insertion block 302 moves towards the middle. Since the outer wall of the insertion block 302 is slidably connected to the inner wall of the partition 2, it can be ensured that it only moves horizontally. Finally, the insertion block 302 disengages from the insertion slot 308 on the inner side wall of the collection box 1, thereby releasing the fixed limit on the partition 2. Then the partition 2 moves downward. Under the action of the X-shaped connecting frame 304, as its overall height changes... When the partition 2 and the base plate 6 move towards the center, the blood collection bottles placed in the circular groove and hole are pushed upward (i.e., the blood collection bottles placed on the base plate 6 move upward), and the blood collection bottle labels are exposed, making it convenient for relevant personnel to quickly read the blood collection bottle information. After reading the information, the partition 2 is reset to the top. At this time, under the elastic action of the spiral spring 307, the rotating column 301 is reset, which drives the connecting plate 306 to rotate in the opposite direction. The insert block 302 is inserted into the insertion slot 308 again to fix and limit the partition 2. The X-shaped connecting frame 304 returns to the initial state, the partition 2 and the base plate 6 are separated, and the blood collection bottle returns to the initial position.

[0040] When the collection is complete and the cover 4 needs to be closed, the contact mechanism 5 on the inner wall of the cover 4 begins to function. As the cover 4 gradually closes, the connecting spring 502 is compressed. Under the elastic action of the connecting spring 502, the reset plate 503 maintains a downward movement trend. The rubber strip 501 fixedly connected to the left side of the reset plate 503 flexibly contacts the top of the blood collection bottle. Due to the elasticity of the connecting spring 502, the reset plate 503 can adaptively adjust according to the different heights of the blood collection bottle, thus providing good support for the top of the blood collection bottle and preventing the blood collection bottle from shaking or tipping over during transportation or movement, ensuring the safety of the blood sample.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
